ABSTRACT:
An in-line laminar flow motionless mixer mixes a low viscosity fluid into a high viscosity fluid. A first conduit section receives the high viscosity fluid and has a first set of slots. Injector nozzles extend into the first conduit section ahead of the slots with orifices which add the low viscosity fluid in the form of sheets. A second tubular section has a second series of slots formed orthogonally to the slots in the first section, and an annular connective jacket encloses the first and second set of slots and provides a flow path between the sections. A flow distributor extends within the respective and provides flow equalization. Method of mixing includes the injection of a low viscosity fluid as a striation. The composite flow is diverted circumferentially radially outwardly causing laminar shear mixing. The outward flow is cut into a smaller individual flows by slots, causing distributive and extensional mixing. The flows are recombined causing further distributive and laminar shear mixing. The combined flow is turned circumferentially radially inwardly and divided into smaller individual flows by a second plurality of slots, causing extensional and shear mixing to the composite flow, and the composite flow is recombined into an outflow.
